' Specification of Letters Patent.

' Application filed March 21.1904. Serial No. 199.308.

Patented Feb. 26, 1908.

citizen of the United States, residin at Philadelphia, in the county of Philade phia and State of Pennsylvania, have invented certain Improvements in Batteries, of which the following is a specification.

This. invention is designed to provide a compact battery cell having increased efficiency and decreased resistance, em loying a es little s ace and having comparativel rge flui. contact surface providing thm septa having am le strength. 7 The construction also provic es means for the. readv assemblage and dissociation of cells, and the ready introduction and removal-of electrodes and excitants.

my invention, igure l-represents a' face view of a-plate or die hragm embodying improvements thereof: 1g. '2 represents a sectionalvi'ew taken on the line-2'2 of Fig.

1: Fig. 3'represents a face view of a late or diaphragm surrounded by a flange a ording stren th and entering into the formation of cu ig. 4- represents a sectional view ta en on the line 4'4 of'Fig. 3:- Fig. 5 represents a' face view of a second form of diaphragm having bordering flanges: Fig. 6 represents a face view of a third form of flange bordered diaphragm: Fig. 7 represents a face view of a fourth form of flange bordered dia hragm: Fig. 8 re resents a fifth form 0 flange bordered (ia hragm: Fig. 9 represents a vertical sectiona view of a cup formed by joining right and left hand flange bordered diaphragms, the section representing a view taken on the line 99 of Fig. 8:- ig. 10 represents a perspective view of a cellconstruction, and Fig. 11 represents a perspective view of a second form of cell construction.

As shown in the drawings, the late or diaphragm 1 has recesses or glan s 2 indented therein, the respective glands being separated from one another by the walls 3 and from the opposite sides of the plate by the walls 4. A large superficial area is thus providedfor each ace of the late and the walls may be made relatively t 'n, for facilitating the action, while maintaining ample strength. In the preferred construction the plates or diaphragms are thus honeycombed in sections surrounded by the solid strips or I b8JldS 5-Wl1l0h provide increased strength.

plates or diaphragms may have borderin anges which provide additional strengt and act in combinations to form on s.

As shown in Figs. 3, 5, and 8, t e top of the bordering flange may be provided with a gas vent 7. One of the upper corners may e provided with an a erture 7 for the passage of a conduit 7 b w ich communicates with the interior of the on s 14, as by the port 7", 'while the other of t e upper corners may have the aperture 7 which permits the A flow of fluid between compartments on either In the accomrianying drawing illustrating side of the cells. One or both of the lower corners may be rovided with an aperture or apertures 8 for t e passa e of fluids.'

As shown in Fig. 8, t e upper flange 6 is provided with the aperture 6 which may be, used .for connecting aconductor to the plate when the latter is an electrode or for connecting a conductor with an electrode con'-, tained in the cup formed by joining together porous earthenware plates.

It will be understood that the cup or compartment shown in Fig. 9 ma be made of porous earthenware for containing an electrodefor may itself be an electrode (of such material as carbon) containing a fluid depolarizer enterin into the action of the cell.

As shown in igs. 6, 7 and 8, one of the passages 8 may be provided with a port 9 for communicating with a cup to be formed by means of the diaphragms, and the passages may be made in feet 10 for supporting the diaphragm.

As shown in Figs. 8 and 9, one of the lower passages 8 may be connected by a channel 11 with a passage 12 having a port 13 adapted for communicatin with the cup 14, the latter being formed l 'oining the flanged borders of right and le t and constructions.

As shown in Figs. 10 and 11, the plates or diaphragms 1 may have the bordering flange 6 at the bottom and two sides and omitted from the top. The diaphragms may be joined to ether to form cups 15 which may be spaced by guides 16 forming compartments 17, as shown in Fig. 10, or to form cups or compartments 18 by placing the diaphragms in series as shown in Fig. 11. The

1 apertures 12.

cells formed as in Fig. 10 have the conduits 19 anti 20 extending through the apertures 8 and the conduit 21 extending through the The conduit 19 has the ori fices 19 communicating with the compartments 17, and the conduit 20 has the orifice 20 communicating by the port 9 with an end cup 15, which distributes to the several cups by the conduit 21 and the orifices 2 1 therein. It will be understood that the several conduits 19, 20 and 21 are to be used for charging and withdrawing the fluids used 7 several cups or compartments and that they are to be made of such section, length and ectrica material as to'provide the requisite e resistance to prevent leaka e of current.

The diaphragms, assemb ed as in Fig. 11, j

have their passages 8 joined together to form conduits through the base of the cell, the conduit having fluid connections by orifices, as 8*, with the desired cups or compartments of the cell thus formed.

It .is to be understood that the term plate as used in the claims is used in its 25 generalineaning and is to be understood as having reference to an electro-chemically active part, whether diaphra m or electrode, employing the characterlstic idea of providing an extended fluid contact surface within comparatively limited bounds. It is to be understood further that by the expression electrochemically active part is to be understood that the art referred to has an active function, as t e function of an electrode or a diaphragm, in the electro-chemical scheme, and is to' be distinguished from the electro-chemically passive cellular structure for holding lead or like material that is to enter into the electrochemical action.

Having described my invention, I claim 1. In an electrochemical apparatus, an electrochemically active part havmg a honeycombed construction on each side thereof providing a-complaratively larger fluid con- 11 comparatively limited tact surface wit borders, substantially as specified.

2. In an electrochemical apparatus, a plate having overlapping indentations in its opposite sides, substantially as specified.
